Aquaman, The Flash and more of DC’s pantheon of heroes suspect Batman of hiding a dark secret that could threaten the very existence of the multiverse!

While investigating a mystery surrounding the strange substance known as Nth Metal, the Justice League makes the most shocking discovery in the history of the DCU…that beneath the known Multiverse exists a much vaster, more terrifying realm called the DARK MULTIVERSE!

A roiling ocean of terrifying, phantom worlds where our greatest fears dwell, a realm where all the stories that should never, ever be told are lurking.

Now, the League has opened the door, and the DARK KNIGHTS will lead the charge as the Dark Multiverse invades our planet in a full scale assault. None of our heroes will be safe, and nothing will ever be the same after this summer’s most epic event, METAL!

So strap in, because this August, comics’ most exciting creative team wants you to release your inner rock god, and follow them on an in-continuity, cosmos-spanning, multiverse-shaking adventure to the wildest, most shocking corners of the DCU.

It’s an epic that will span generations-but how does it connect to the origins of one of DC’s most legendary heroes?

The great comics event of summer 2017 is about to begin courtesy of superstar writers Scott Snyder and James Tynion III and illustrated by a master class of comics artists: Andy Kubert, Jim Lee and John Romita Jr.! You do not want to miss this one!
